SAFETY-CATCH EoR BRoocHEs AND SIMILA ARTICLES.

Application filed October 18, 1918.

To all whom it may concern Be it known that we, GEORGE WILLIAM DOVER and WILLIAM HENRY HUGHES, citizens of the United States, and residents, respectively, of Cranston, in the county of Providence and State of Rhode Island, and of Providence, in the county of Providence and State of Rhode Island, have jointly invented a new and useful Improvement in Safety-Catches for Brooches and Similar Articles, of which the following is a specification.

Safety catches for brooches and similar articles of jewelry are necessarily small and delicate in construction. They must also be sufficiently strong so as to securely hold the pin tongue in the closed position. As heretofore usually constructed, the movable or locking member of the catch is weak in construction and is liable to become distorted or unlocked when in use, thereby ruining the utility of the catch.

The object of our invention is to improve the construction of a safety catch for brooches and similar articles whereby, the strength of the catch is greatly increased and the pin-tongue of a brooch more securely held in the closed position in the catch, than has heretofore been done.

Our invention consists in the peculiar and novel construction of a safety catch for brooches and similar articles, said safety catch having details of construction, as will be more fully set forth hereinafter and claimed.

Figure 1 is a side view of the catch end of a brooch provided with our improved safety catch.

Fig. 2 is an end view of the catch end of the brooch showing the locking member of the catch in the closed or locked position in full lines and in the open position in broken lines.

Fig. 3 is a central longitudinal sectional view through the brooch and catch, taken on line 3.3 of Fig. 2, with the locking member in the closed position.

Fig. a is a transverse sectional view through the brooch and catch, taken on line 4:.4 of Fig. 1, with the locking member in the closed position.

Fig. 5 is an inner face View of the blank Specification of Letters Patent.

from which the keeper of the catch is formed. A Fig. 6 is an edge view of the keeper blank.

Fig. .7 is an inner face view of the blank frorln which the locking member is formed, an

Fig. 8 is an edge view of the locking member blank. I

All of the figures in the drawing are greatly enlarged to more clearly show our inventlon.

In the drawings, 9 indicates the body of a brooch or similar articles of jewelry, 10 a pin tongue and 11 our improved safety catch which consists of a relatively stationary keeper 12 and a pivoted locking member 13. The keeper 12 is first struck out in blank form, as shown in Figs. 5 and 6. 'It is then bent up U shape and has a base portion 14 and flat sides 15.15 in each ofwhich is an oppositely disposed bearing 16, adjacent 'the base 14:. Each'side 15 alsofhas a curved end 17 in which is a pin-tongue opening 18 and an off center projection forming a stop 19 as shown more clearly in Fig. 5. The locking member 13 is first struck out in blank form, as shown in Figs. 7 and 8.

tends from the pintles 20.20 to a curved cap" the curved ends 17.17 of the keeper and has the same width as the keeper, as shown in Fig. 3. A pin-tongue locking groove 23 is formed in the underside of the cap 22 on a line with the pintongue openings 18.18 in the keeper, when the locking member is closed and a bent up operating member 24: is formed centrally on the end of the cap 22, the adjacent end portions 25.25 of the cap 22 engaging with the stops 19.19 on the keeper, limits the closing movement of the locking member.

When in use the base portion 1 1 of the keeper is secured to a brooch or similar artilar article by solder or other means, on a line with and in a position for the pointed end of the pin-tongue to enter the pin-tongue 22 which fits over l and has the oppositely openings 18.18 in the catch, when the looking member is in the open position, as shown in broken lines in Fig. 2. The locking memJber is then closed by the operating member 2%. The ends 25.25 on the cap 20 engaging with the stops 19.19 on the keeper limits the closing movement of the locking member and brings the locking groove 23 in the cap over the pin-tongue. The spring of the pin tongue now forces the pin-tongue into the locking groove 28 in the cap and the pin-tongue being held from sidewise movement by the sides of the pin-tongue openings 18.18 locks the locking member in the closed position. A pressure on the pin-tongue toward the bearings 16.16 unlocks the locking member, which may now be opened, by the operating member 24: to release the pin-tongue.

Having thus described our invention we claim as new.

- 1. A safety catch for brooches and similar articles, comprising a U-shaped keeper having a base portion and two sides, each side having a closed bearing adjacent the base portion, a curved end, a projection forming a stop on the curved end and a pin-tongue opening in the curved end, a lockingmember having integral pintles in the bearings in the keeper, a shank having the same width as the keeper, a curved cap on the shank and having a transverse pin-tongue locking groove and an operating member on the end of the curved cap. 7

2. A safety catch for brooches and articles, comprising a U shaped keeper having a flat base portion and two sides, each side having a closed bearing adjacent the base portion, acurved end, an 05 center pro similar bearings 16.16, a straight shank jection forming a stop on th curved end and acentral pin-tongue opening in the curved end, a locking member having pintles in the integral pintle bearings in the keeper, a shank having a movable fit between the sides of the keeper and a curved cap on the shank fitting over the curved ends of the keeper, when the locking member is in the closed position, said cap having the same width as the keeper, a transverse pin-tongue locking groove and an operating member on the end of the cap 3. A safety catch for brooches and similar articles comprising a keeper 12 having a flat base portion 1% and sides 15.15, each of which has a closed bearing 16, adjacent the base portion 14, a curved end 17 in which is a pin-tongue opening 18 and on which is a projection forming a stop 19, a locking mem ber 13 having integral pintles 20.20 in the 21 having a movable fit between the sides 15.15 of the keeper, a curved cap 22, which when closed, fits over the curved ends 17.17 of the keeper and has the same width as the keeper, said cap 22 having a transverse pin-tongue looking groove 23 in its underside, a bent up operating member 24: on its end and end portions 25.25 which engaging with the stops 19.19 on the keeper limits the closing movement of the locking member and a pintongue springing into the pin-tongue locking groove 23 in the cap locks the locking member in the locked position as described.

In testimony whereof, we have signed our names to this specification.
